Sound Reinforcement Loudspeaker Systems

A broad range of professional loudspeakers that are the ultimate for large venue, music, vocal and instrument reinforcement applications. Our SR Series II loudspeakers have become the first choice of musicians, large club owners, DJ's and sound engineers worldwide.

Key Features:

VGC™ low frequency transducers are the ultimate in reliability, low distortion and low power compression.
Large format, pure titanium diaphragm compression drivers with Coherent Wave R phase plug on an Optimized Aperture™ horn for extremely low midband distortion.
SR Series II cabinets have tongue and groove construction of multi-laminate crossgrain void-fee plywood, and are bonded under high pressure using high temperature adhesives and internal crossbracing. The result is an enclosure of exceptional strength and integrity.
Advanced crossover network design with the flexibility of both 1/4" and Neutrik Speakon connectors for flexibility of hookup.
600 - 1200W power handling capabilities throughout the range.
